Sometimes the ATS-only setting worked and sometimes it didn't and in older versions it may not have existed. We have not had time to fully debug and QE. When distributed PGRs/reservation support is added it will not be a issue, so we have been concentration on that instead of debugging each vsphere version individually due to lack of time/resources. SUSE's implementation does support distributed PGRs, so you should be able to use it now. Do you mean 5.0 or 5.5 btw? And if 5.0, just wondering why the older version. > and I myself use oVirt (RHEV). the default protocol is iSCSI. For RHEV, RHCS iSCSI is supported with the current version. It works like a normal old iSCSI target. There were no changes done to RHEV for this, so I think it should work just fine with upstream/downstream ceph iscsi and oVirt too. > I know that openstack/cinder work well with ceph and proxmox (just > heard) too.
